摘要
文章介绍了LTE-Advanced系统中的载波聚合技术,该技术能解决与LTE载波的兼容性,并满足频带资源的需求。文中首先阐述了载波聚合技术的研究背景及优势,随后对载波聚合的应用场景,切换分析,非对称载波聚合,传输数据流的聚合方式等几方面内容研究状况进行了综述。最后,对进一步需要研究的问题进行了讨论。
Carrier aggregation technology in LTE-Advanced system is firstly introduced, which can solve the compatibility between LTE-Advanced system and LTE system, and the bandwidth requirements of LTE-Advanced system. Then reseach background and advantages of carrier aggregation technology are presented, and the implements of carrier aggregation are introduced, which include application scene, hand over, asymmetric carrier aggregation and data streams aggregation and so on. Finally, these problems that should be further studied are discussed.
